SPECIFICATION forming part of VLem-.ers Patent No. 723,983, dated March 31, 1903. Application filed March 5. 1898. vSerial No. 672.641. (No model.)

To all wtmn itmay concern:

Be it known that I, HOMER BROOKE, of Jersey City, in the countyof Hudson and State of New Jersey, have invented a new and useful Improvement in Devices for Cutting Molten Material and DistributingY the Same, of which the following is a specification.

The present invention relates to devices for cutting or separating molten material, and especially is designed for cutting a stream of flowing molten glass into unformed molten masses of predetermined quantity and distributing the same into suitable receptacles.

The device which is the subject of the present invention is particularly designed for use in connection with an apparatus for flowing 'molten glass,such as is described and claimed in Letters Patent No. 588,318, granted to me August 17, 1897, and also as described in au application for LettersfPatent filed by me ebruary 10, 1898," and serially numbered 669,783. In said patent and application there is described a construction which discharges the molten glass contained in a furnace or other receptacle by flowing the same therefrom by means of a movable conduit or mouth,

, the ow of the molten glass being control-led by raising or lowering the movable conduit, as particularlydescribed in said patent and application.

In the drawings accompanying the present application I have illustrated a form of construction embodying the features of my invention, in which drawings- Figure-1 is a View, partly in central vertical section and partly in side elevation. Fig. 2 is a plan View, certain parts being broken away. Fig. B'is a viewin side elevation, showing the device attached to a movable mouth or conduitof a furnace. Fig. 4. is a detail view in plan of the turn-table-operating mechanism.. Fig. 5 illustrates diagram matically the sequence of positions of the cutting-knives' and receptacles in the operation of cuttingr the owing stream of molten glass.

Like gures of reference refer to like parts throughout the several views of the drawings.

Referring to the drawings in detail, 1 designates a `central vertical shaft which is screw-threaded on its lower end. This central shaft is supported in an internallythreaded sleeve 2, carrying a initier-gear mesh- .cam-track 8.

ing with a gear 3.on the end of-shaft 4, journaled in the trolley-frame 4a, which also carries the threaded sleeve 2.

the central shaft and rotating thereabout in opposite directions. The upper series of knives consist of cup or trough shaped receptacles having a cutting edge and are designed to cut thestream of flowing molten glass and momentarily lift the same and discharge it into a receptacle beneath. The lower series of knives lconsist of plain fiat blades constructed to operate in conjunction with the upper series in the desired manner.

The means which I have shown in the drawings for turning the two series of knives in opposite directions consists of a beveled gear 5, mounted on a shaft 6, said shaft being supported at one end in the hub 7 of a cam-track 8, which hub is secured to the shaft 1. The shaft l6 also has a bearing intermediate its ends in the cam-track 8. Any desired means may be availed of for turning the shaft 6, in the drawings a crank 9 being shown for this purpose;

The upper series of knives are pivoted in brackets 10, extending from a hub 11, which is made integral with or has secured to it a bevel-gear12, which is in mesh with the bevelgear 5. Each of the arms (of which I have shown four) of the upper series is constructed as follows: kThe bent arm 13 is provided with asocket-piece 14, fitting into a socket formed in the arm l5, said piece being secured in any desired manner to the arm 15, so that said arm 15 may oscillate freely thereon, the means shown consisting of a pin 16, projecting through the arm 15 into a groove 17, cut in the socket-piece 14 and extending part way around the same. These parts are supported by a cam-roller 18, suitably secured to the arm 15 by means of a shoulder 19 and a collar 20, said cam-roller resting upon the The arm 15 carries at its inner end a trip 21, which comes in contact with an arm 22 in its path of revolution, thus oscillating the arm 15 and the cutting-knife carried thereon. The said cutting-knife, secured to the end of arm 15, is shown as consisting of a cup or trough shaped receptacle 23, oneside of which is provided with a concave cutting edge 24. It will be apparent,

The cutting-- knives consist of two series, radiating from ICO however, that this upper knife maybe other?` wise constructed.

The lower series of cutting-knives are carried on a hub 25, which has formed integral therewith or secured thereto a beveled gear 26, which meshes with the beveled gear 5., wherebyit is driven in an opposite direction to the beveled gear l2, which drives the upper series of knives. ries of knives consists of a blade 27, carried on the end of an arm 2S, extending from am hub 25.

Beneath the lower series of arms is located a turn-table 29, which carries a number of molds or receptacles 30, which may be designed togive any desired shape to the molten material contained therein or may serve simply as temporary containing devices from which the molten masses may be taken and given final formation by other apparatus. As shown in the drawings, the turn-table is illustrated as being provided with eight of these molds; but it will be evident that any desired number may be placed thereon. This turn-tablelis designed to have intermittent motion imparted to it, so that the receptacles shall be brought to position underneath the cutting-knives at the proper time to receive the stream of molten glass. The devices shown for imparting this intermittent motion consist of a gear 30', secured to the turn-table, which is driven bya smaller gearwheel 3l, this gear-wheel 3l being secured to a shaft 32, jourualed in an arm 33, projecting from a boss or hub 34, secured to the shaft l. Movement is given to the gear 31 by means of pins 35, engaginf.; a star-wheel 36, secured to the end of the shaft 32, said pins 35 being secured to and projecting downwardly from the arms 28.

The whole apparatus is designed to be moved into and out of operating position relatively to a furnace mouth or conduit, and in the drawings I have illustrated for this purpose the trolley mechanism heretofore de` scribed; but any other suitable means of supportingand conveying the cutting device may be availed of. Preferably the parts will be connected to the movable conduit or mouth, connecting-rod 38, secured to the central shaft 1, being shown for this purpose.

The operation of the device will now be apparent. Assuming that the parts are in position as shown in Fig. 3, the conduit 37 will be lowered until the molten glass flows there-` from into one of the receptacles 30. Motion being given to the several parts, the cuttingknives approach each other, as shown in the rst position illustrated inv Fig. 5, and sever the molten stream, as shown in the second position illustrated in Fig. 5. The next step immediately following the completion of the cutting operation is the rising of the upper cup or trough shaped knife, which movement is impartedto it by the cam-track 8, as illustrated in Fig. 3. Simultaneously with this rising movement of the upper knife it is tilted the arm 22.

Each of the lower sep ina direction opposite to its path 0f"`movement by the trip 21 coming in contactwith By this rising and simultaneous tilting motion the molten glass is momentarily'supported in the cup or trough shaped receptacle while an empty receptacle is being brought to position underneath to receive the molten glass. The tilting of the cup-shaped receptacle also performs the office of leading the cut-off end away from the end into the How of the molten glass, so that it becomes. homogeneous and prevents the shear-marks from showing in the article of glass subsequently formed therefrom. The third of the series of diagrammatic views illustrated in Fig. 5 shows the parts in the position just described, the cupeshaped receptacle or knife being only partially tilted. In the fourth of the series of illustrations the tilting operation has been completed, and the molten glass is discharged from the cup-shaped receptacle into the receptacle underneath. The further operation of the device completely discharges the molten glass from the cup-shaped recep tacle, and the same passes away, resuming ils normal cutting position by the action of gravity, being constructed so as to do this. The molten glass is now flowing directly into the receptacle, and the next succeeding pair of knives are approaching to repeat the operation just described.

Of course it will be understood that I do not limit myself to the precise construction of devices here illustrated, as I consider myself to be entitled to broadly cover all means for cutting or separating a stream of flowing molten material into unformed molten masses and discharging the cut-off portions.
